Catalyst free decarboxylative trichloromethylation of aldimines†
Abstract
A catalyst free decarboxylative trichloromethylation of imines to afford different trichloromethyl sulfonyl and sulfinyl amines has been presented. Only DMSO as a solvent at room temperature was necessary to provide the corresponding products in good to high isolated yields. A highly diastereoselective version was carried out, leading to the sulfinylimine with good yield and near perfect diastereoselectivity. Regarding the reaction profile, ATR-FTIR spectroscopy was employed to support the entire mechanism and also to provide details on the trichloroacetate salts behavior against electrophiles and in the presence of different solvents.
